Abstract K4H2CoW12O40·2TiO2·9H2O crystallizes from an aqueous solution of Na2WO4, Co(OAc)2 and Ti(SO4)2. The compound has very similar i.r. and u.v. spectra to those of [CoW12O40]6− and [CoW11TiO40]8− but its polarographic behaviour is different from that of [CoW11TiO40]8− and exhibits only reduction of tungsten(VI). A single crystal structural analysis indicates that this compound consists of the heteropolyanion [CoW12O40]6−, titanium–oxygen chain, potassium ions and water molecules.
